Huge as Turrican and Super Turrican were in Europe, Super Turrican never managed to make it on the NES despite apparently being an essentially completed game. You can find -possibly even buy- all the proof you need over at this NES Super Turrican Prototype eBay auction. It's a NTSC version of Super Turrican on a 22 years old EPROM cartridge from SEIKA / Manfred Trenz for the Nintendo Entertainment System.
The thing is quite obviously extremely rare and thus expensive, though it does admittedly look rather impressive. Seller ships worldwide.
